The gene for Escherichia coli ribonuclease P (RNase P) protein (also known as C5 protein) and its mutant C5-C113A have been expressed as GST fusion proteins in E. coli at a high level. After cleavage of the fusion protein, highly purified functional C5 protein is obtained that can be crystallized with 2.5-2.6 M (NH(4))(2)HPO(4)/(NH(4))H(2)PO(4) pH 7.0 at room temperature. These crystals are suitable for X-ray analysis, belong to the space group P3(1)21 or P3(2)21 (unit-cell parameters a = b = 66.67, c = 142.09 A) and diffract to 2.9 A at 100 K using sorbitol and glycerol as cryoprotectants. For three molecules in the asymmetric unit a V(M) of 2.17 A(3) Da(-1) was calculated.
